Long-term rental The property presents a fair investment opportunity for long-term rental, with a gross yield of 4.1% that aligns with market expectations. However, the proximity to major transport routes enhances its appeal to tenants seeking suburban living near Lisbon. Family rental Given its size and location, this 3-bed duplex is well-suited for family rentals, providing ample space and accessibility to amenities in the area. Although not a bargain, it can serve a steady demand for families looking for comfortable housing options in Seixal. Buy-and-hold This investment can serve a buy-and-hold strategy, given its relatively stable value with a minimal gap from fair value at 3.7%. While the condition is only moderate at 50/100, the location's potential for appreciation could offer long-term benefits without being considered undervalued.
Tenant turnover risk The tenant stability score of 70/100 indicates a potential risk of higher turnover, which could lead to increased vacancy rates and associated costs.
